After the annexation of Awadh, the first British 'revenue settlement' imposed there was known as:

Summary Settlement

The correct answer is Option (3) → Summary Settlement

The term "Summary Settlement" was used to describe the initial British revenue settlement imposed in Awadh (Oudh) after its annexation.

A chain of grievances in Awadh linked prince, taluqdar, peasant and sepoy. In different ways they came to identify firangi raj with the end of their world – the breakdown of things they valued, respected and held dear. A whole complex of emotions and issues, traditions and loyalties worked themselves out in the revolt of 1857. In Awadh, more than anywhere else, the revolt became an expression of popular resistance to an alien order.

The annexation displaced not just the Nawab. It also dispossessed the taluqdars of the region. The countryside of Awadh was dotted with the estates and forts of taluqdars who for many generations had controlled land and power in the countryside. Before the coming of the British, taluqdars maintained armed retainers, built forts, and enjoyed a degree of autonomy, as long as they accepted the suzerainty of the Nawab and paid the revenue of their taluqs. Some of the bigger taluqdars had as many as 12,000 footsoldiers and even the smaller ones had about 200. The British were unwilling to tolerate the power of the taluqdars. Immediately after the annexation, the taluqdars were disarmed and their forts destroyed. The British land revenue policy further undermined the position and authority of the taluqdars. After annexation, the first British revenue settlement, known as the Summary Settlement of 1856, was based on the assumption that the taluqdars were interlopers with no permanent stakes in the land: they had established their hold over land through force and fraud. The Summary Settlement proceeded to remove the taluqdars wherever possible. Figures show that in pre-British times, taluqdars had held 67 per cent of the total number of villages in Awadh; by the Summary Settlement, this number had come down to 38 per cent. The taluqdars of southern Awadh were the hardest hit and some lost more than half of the total number of villages they had previously held.
